The analysis can help defuse the debate over the value of a liberals-arts education versus a career-focused one, says Matthew Sigelman, chief executive at the job-market-analytics company Burning Glass Technologies.

But many employers are also looking for applicants with additional, specific skills, such as knowledge of Java or other programming languages, or proficiency with graphic-design tools like InDesign or Adobe Suite. "It’s not a matter of shutting down the classics department and turning it into a business degree," he says.
